TechSEO is a free website crawler for technical SEO audits. It visits your pages the way a search engine does, explains each problem in plain English and gives you tools to fix it. No signup, nothing to install. Pick a tool on the Tools page or run the full crawl on the home page.
Find the problems
- Broken links and errors: internal and external links that return 4xx, 5xx or no response, with the page each link was found on.
- Redirects: every 3xx redirect, its final destination and redirect chains.
- Page titles and meta descriptions: missing, duplicate, too long or too short.
- Headings and images: missing, multiple and duplicate H1 headings, broken images and images without alt text.
- Indexing: noindex, canonical and X-Robots-Tag settings, and which pages can appear in Google.
- Duplicate and near-duplicate content: pages that are exactly or almost the same as another page.
- robots.txt checker: your rules, the sitemaps listed in it and the URLs it blocks.
- Hreflang audit: valid language codes, self-references, return links and broken targets.
- Structured data: JSON-LD and microdata, with warnings for missing fields.
- Accessibility basics: empty links, unlabelled form fields, skipped headings, missing language and blocked zoom.
- Page speed: Google PageSpeed Insights for mobile and desktop, with fixes in plain English.
- Spelling and grammar: typos and grammar mistakes in the text of any crawled page.
Fix them
- Redirect rules maker: turns redirect chains and broken pages into rules you can paste into .htaccess or Nginx, or download as a list.
- Title and description editor: rewrite weak page text with a live Google preview and character counts, then download the changes as a CSV.
- Fix these first: the biggest problems ranked by impact and effort, each with a plain-English explanation, a tick box and a progress bar.
Keep track and share
- XML sitemap generator: download a sitemap of every indexable page the crawl found.
- CSV export of every report.
- Save and compare: keep a report for 30 days, crawl again after your fixes and see exactly what improved.
- Shareable report: send a private link to a client or save the report as a PDF. No account needed.
On the way
These need a sign-in or extra servers, so they are not available yet: Google Search Console and Analytics connections, scheduled crawls by email and JavaScript rendering.
